truBIMTM is the process of achieving a completely integrated information database model accompanied by a 3D graphical
representation of the facility and site. Use truBIMTM to prepopulate your predictive and preventative maintenance application with standardized consistent information allowing for easy retieval in times of crisis. LEVELS of MODELING: 
Design Intent Modeling (DIM) is the level of detail that an Architect or Engineer models do to the fact of lack of information. They put into the model spacial reservations that represent basic object shapes.
Work Intent Modeling (WIM) is the level of detail found in installation or shop drawing documentation. The sub contractor knows what they are buying, and if provided by the manufacturer, will use their 3D widget to replace the DIM objects in the model.
Building Information Modeling (BIM) as described here is the act of combining 3D modeling and basic design information into one cad agnostic widget for the sole use of data information extraction.
